Previously, Telos had used Sun Microsystem Inc.s LDAP server product. But because Sun prices per user account rather than per server, as does Sleepycat, the cost of deployment was too steep, according to Stephen Williams, director of SGSN (Serving GPRS [General Packet Radio Service] Support Node) product development, in Vancouver. "[Berkeley DB XML] is going to save us a lot of money," Williams said. "Many products are big iron and carry a big-iron price tag with them. The Oracle [Corp.] or any other [relational database management system] can cost many thousands of dollars, depending on the number of seats or users. The iPlanet product [from Sun], the best pricing we can get is 50 cents per [supported cell phone user]. We just know Berkeley DB XML product will be lower."Sleepycats software is a typical open-source scheme: either free to download and use or for a fee to ship a product without making the application source code freely available. The company has about 200 million licensed users, of which about 200 are paying customers, officials said. Unlimited replication rights for Berkeley DB sell for $300,000. Sleepycat writes proprietary-like licenses for those companies that prefer to keep their codes to themselves, with average selling prices of $150,000 for the transactional engine, officials said. Berkeley DB XML will be priced at $15,000 per server, with the same free-or-fee terms.
Williams estimated that Sleepycats software would save Telos thousands of dollars per deployment of its SGSN product, which is a product that handles packet data to mobile phones.
